Application filed August 1'7, 1914. Serial No. 857,030.

' citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in Motors, of which the following is a specification.

' This invention relates to a motor, and particularly pertains to a rotary motor of the internal combustion type.

It is the object of this invention to provide an internal combustion motor in Which the force exerted by the explosion of the gaseous mixture will be delivered directly to a rotary shaft without the interpositioning of reciprocating parts.

Another object is to provide a motor having revoluble blades or vanes connected to a rotary shaft and so arranged that-an intermittent rotary movement of the blades will be effected by the explosion of a gaseous mixture between certain of the blades at frequent intervals, and in which the intermittent movement of the blades will effect a constant rotation of the shaft.

Another object is to provide an internal combustion rotary motor in which the explosion of a compressed gaseous mixture between one pair of blades will effect the compression of a charge of gaseous mixture between a succeeding pair of blades; the compressed charge operating when pressed to a predetermined degree to advance the preceding blade and thereby move the compressed charge to the point of ignition so that a series of explosive impulses will be imparted to the rotor member in one revolution thereof from one point of ignition.

Another object is to provide an internal combustion motor in which the intake of eX- plosive mixture, compression, explosion and scavenging of the burnt mixture will be efiected a plurality of times during onerotation of the rotor.

A further object is to provide a motor capable of generating high power in proportion to its size and weight, and which consists of few simple parts readily manufactured and assembled.

More specifically, 15 indicates a cylindrical water-jacketed casing fitted with end plates 16 and 17 detachably secured thereto by means of bolts 18 which pass through the end plates 16 and 17 and are screwed in the ends of the cylinder 15. The end plate 16 s'formed with a boss 19 constituting a bearmg for a tubular shaft 20 which passes 'therethrough and has an enlarged portion ,channels on the inner face of the end plate 16 and form packing members. Formed on the hub 21 is a pair of oppositely extending blades 23 and 24 which diverge outwardly from their point of juncture with the hub 21 and with their side faces extending in radial relation to the center of the hub which is .the axis of the cylinder 15. The outer faces of the blades 23 and 24 are curved to conof the outer face of the hub 21.

Projecting through the tubular shaft 20 is a shaft 25 which passes through a boss 26 on the end plate 17 and bears therein, and mounted on the shaft 25 is a hub 27 extending between the end of the hub 21 and the inner face of the end plate 17. Mounted on the hub 27 is a pair of oppositely disposed blades 28 and 29 corresponding in construction to the blades 23 and 24; the outer ends of the blades 23 and 24 projecting over the hub 27 and the outer ends of the blades 28 and 29 extending over the hub 21 and forming the interior of the cylinder 15 into a series of four chambers arranged between the blades in each of which chambers a charge of explosive mixture may be drawn, compressed, exploded and scavenged successive1y.,

The shafts 20 and 25 are designed to rotate in but one and the same direction and as a meansfor preventing revers'e rotation each shaft is provided with a roller ratchet comprising disks 30 and 31 keyed on the shafts 20 and 25 respectively having notches 32 formed on their peripheries in which rollers 33 are mounted; the rollers 33 being adapted to travel up inclined walls of the notches 32 into engagement with the inner .circumferential faces of annular flanges 34 and 35 formed on the end plates 16 and 17 exteriorly thereof. The construction of the roller ratchets is particularly shown in Fig. 6 which illustrates a common form of such ratchets which permit the ratchet disks to rotate freely in the direction indicated by the arrow a in Fig. 6, but inhibit their rotation in reverse direction.

A corresponding pair of roller ratchet disks 36-and 37 are mounted on the outer ends of the shafts 20 and 25 Where the shaft 25 projects beyond the outer end of the shaft 20; the disks 36 and 37 being arranged alongside of each other with the rollers 38 and 39 carried thereby adapted to engage the inner circumferential wall of a fly wheel 40 mounted on a drive shaft 41 disposed in alinement with the shaft 25.

The. disks 36 and 37, however, are arranged with the inclined faces of the notches 32 thereon extending in the opposite direction to the inclination of the inclined notches 32 on the disks 30 and 31 so that intermittent rotary movement of the shafts 20 and 25 willbe imparted to the fly wheel 40 and the shaft 41 to rotate the latter continuously in one direction. I

The ratchet disk 31 is housed in the flange 35 by means of an end plate 42 secured; to

the flange 35, and the ratchet disks 30, .36 and'37 and the flywheel 40 are incased in a housing 43 secured to the end plate 16; the hous1ng43 being adapted to contain a quantity of oil by which the various rotat ng parts are lubricated. As a means for distributing thelubricant from the housing 43 to the bearings at the opposite end of the casing, a coiled tube 44 havin an enlarged open outer end 45 is mounte on a disk 46 carried by the tubular shaft, the inner end of which tube passes through the tubular shaft 20 and is adapted to register with an opening 47 in the shaft 25 communicating with a passage 48 having outlets leading to the bearings of the shaft 25.

The tube 44 on rotating with the shaft 20 in the direction indicated by the arrow in Fig. 7 causes the lubricating oil to be forced into the open end 45 of the tube and be thereby delivered through the tube 44 to the distributing passage 48 in the shaft 25.

Formed in the upper wall of the cylinder 15 is a series of intake openings 50 which are adapted to be connected to a suitable source of gas supply and formed in the side of the cylinder 15 is a series of exhaust ports 51 arranged at a point on the cylinder at right angles to the intake openings.

A spark plug 52 is mounted in an aperture 53 in the cylinder 15 at a point to one side of the vertical center of the casing opposite the side on which the exhaust ports 51 are formed.

The blades 23, 24, 28, and 29 are fitted with packing members 54 on their outer curved faces extending longitudinally thereof and mounted in channels 55 formed in the blades. The packing members 54 are L-shaped in cross section with one of the members slidably engaging one side of the channel 55, as-particularly shown in .Fig. 5, and interposed between the bottom of the channel 55 and the other member of the packing 54 is a plate spring 56 which normally operates to maintain the packing member 54 in slidable contact with the inner circumferential wall of the cylinder 15. The ends of the blades, 23, 24, 28 and 29 are also provided with packing members 57 which extend in radial channels formed on the ends of the blades and correspond in construction to the packing members 54;

plate springs 58 hearing against the packing members 57 to maintain them in close slidlng contact wlththe inner faces of the end plates 16 and 17.

naaae ea between the blades 29 and 24 open to the intake ports 50, the chamber between the blades 23 and 28 about to open to the exhaust ports 1 51, and the chamber between the blades 24 tween the blades 24 and 28 containing the compressed explosive charge positioned in communication with the aperture 53 containing the spark plug 52. At this momenta spark is formed by the plug 52 in the usual manner, thereby ignitin the compressed explosive charge which Wlll expand and exert opposed pressures between the blades 24 and 28' tending to advance the blades in opposite directions in relation to each other. The

' blade 24 is prevented from moving rearwardly by the action of the roller ratchet member on the shaft 20 so that the impulse effected by the expansion of the exploded gases between the blades 28 and 24 will be exerted on the blade 28, therebyadvancing the latter and the blade 29 simultaneously therewith; the blades 23 and 24 remaining stationary as illustrated in Fig. 9.

This movement of the blades 28 and 29 effects an impulsive rotary movement of the shaft 25 which movement is transmitted through the roller ratchet members 39 to the fly wheel 40, thereby rotating the drive shaft 41. The advance movement of the blade 28 effects the scavenging of the previously burned charge in advance of the blade 28 through the exhaust ports 51 and the ad- Vance movement of the blade 29 operates to compress the explosive charge between the blades 29 and 24; the back. pressure on the blade 24 induced by the explosion and expanding of the gases in advance of the blade holding this blade stationary in oppo sition to the pressure exerted thereagainst by the compression of the charge induced by the blade 29. The moment the compression of the charge exerts a pressure on the blade 24 in excess of the pressure exerted by the expanding exploded charge which gradually diminishes, the blades 23 and 24, 28 and 29 will again advance in unison as before described in reference to'Fig. 8, thus positioning the chamber between the blades 29 and 24 containing the compressed explosive charge in communication with the aperture 53 containing the spark plug 52 and the operation is repeated.

iii

In the next impulse the blade24 will be advanced and a rotary impulse will be transmitted to the fly wheel 40 through the medium of the roller ratchet 38; the blade 29 being held against retrograde movement by the action of theroller ratchet member 31.

In this manner a series of four impulses will be imparted to the shafts 20 and 25 during each revolution thereof, which impulses willbe transmitted to the fly wheel 40 and operate to rotate the latter and the shaft 41 continuously in one direction; the advance movement of each blade in effecting such impulse acting to scavenge a previously burned charge and to simultaneously compress a fresh explosive charge.
